Enum pkcs7::ContentInfo

pub enum ContentInfo<'a> {
    Data(Option<DataContent<'a>>),
    EncryptedData(Option<EncryptedDataContent<'a>>),
    Other((ContentType, Option<OctetString<'a>>)),
}

Content exchanged between entities RFC 5652 § 3

ContentInfo ::= SEQUENCE {
  contentType ContentType,
  content
    [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL }

Variants

Data(Option<DataContent<'a>>)

Content type data

EncryptedData(Option<EncryptedDataContent<'a>>)

Content type encrypted-data

Other((ContentType, Option<OctetString<'a>>))

Catch-all case for content types that are not explicitly supported

• signed-data
• enveloped-data
• signed-and-enveloped-data
• digested-data
